The Opioid Crisis Examined, Anatolly Zekhtser Nov 2019

The Opioid Crisis Examined, Anatolly Zekhtser

BIO4960: Practicum in Biology I

The Opioid Crisis is a national crisis affecting public, social, and economic healthcare. Nearly 50,000 deaths were caused by opioid overdoses in 2017. Current treatments of opioid addictions include the use of methadone and buprenorphine. These medications have been known to reduce opioid dependency, lower tolerances, increase the opioid overdose threshold, and lower overdose mortality. An analysis was conducted on prominent research studies investigating the effectiveness, safety, side effects, and influence of Methadone and Buprenorphine. The meta-analysis confirmed that both drugs are effective opioid agonists that contribute to decreased opioid dependence and increased opioid abstinence. Due to a series of …

Inferred Function And Dynamics Of Microbial Communities From The Northern Gulf Of Mexico, Deepesh Tourani Nov 2019

Inferred Function And Dynamics Of Microbial Communities From The Northern Gulf Of Mexico, Deepesh Tourani

HCNSO Student Theses and Dissertations

Microbial communities, or microbiomes, are the major drivers of global biogeochemical cycles, acting as primary producers and decomposers across the water column in the oceans. Thus, they reflect changes in physicochemical properties and nutrient composition of the ocean. However, this correlation between ecological changes and the function of marine microbiomes is poorly understood. Large-scale oceanic events such as the bottom-water oxygen-depleted zone (i.e., “dead zone”) and the Deepwater Horizon oil spill in the Gulf of Mexico (GoM) render the ecosystem fragile. These events decrease survival rates of pelagic and coastal macrofauna and affect the biodiversity of the region. As part …

Bovidae, the largest family in Pecora infraorder, are characterized by a striking variability in diploid number of chromosomes between species and among individuals within a species. The bovid X chromosome is also remarkably variable, with several morphological types in the family. Here we built a detailed chromosome map of musk ox (Ovibos moschatus), a relic species originating from Pleistocene megafauna, with dromedary and human probes using chromosome painting. We trace chromosomal rearrangements during Bovidae evolution by comparing species already studied by chromosome painting. The musk ox karyotype differs from the ancestral pecoran karyotype by six fusions, one fission, …

Antibiotics Overuse And Bacterial Resistance, Mir Saleem, Brett Deters, Adam De La Bastide, Martha Korzen Oct 2019

Antibiotics Overuse And Bacterial Resistance, Mir Saleem, Brett Deters, Adam De La Bastide, Martha Korzen

Biology Faculty Articles

Antibiotic usage has become very widespread, as they are used to treat so many infectious diseases today. Antimicrobial agents exert their actions via different mechanisms including blockage of cell wall synthesis, interference of protein and/or nucleic acid synthesis, interruption of cell membrane structure, and inhibition of a metabolic pathway. The treatment of bacterial infections with antimicrobial agents has become more difficult due to the capability of bacteria to develop resistance to antibiotics. Erroneous diagnosing, misconceptions, and improper physician-patient dynamics have led to overuse of antibiotics and the emergence of drug-resistant bacteria. Bacterial colonies have been shown to confer advantageous genetic …


Technology In University Physical Activity Courses: A Mini-Ethnographic Case Study, Dannon G. Cox, Jennifer M. Krause, Mark A. Smith Oct 2019

Technology In University Physical Activity Courses: A Mini-Ethnographic Case Study, Dannon G. Cox, Jennifer M. Krause, Mark A. Smith

The Qualitative Report

As younger generations become increasingly reliant on technology, higher educational institutions must continually attempt to stay with or ahead of the curve to foster 21st century teaching and learning. College and university physical activity courses (PACs) are encouraged to incorporate technology for effective pedagogical practices. No qualitative research has specifically examined the culture of PACs instructors’ attitudes and experiences with technology as a pedagogical tool. A mini-ethnographic case study explored the use of technology among seven graduate teaching assistants who shared their pedagogical experiences, teaching practices, and perceptions of technology within PACs. Using an interpretive phenomenological analysis, composite narrative accounts …

The Complete Mitochondrial Genome Of An Atlantic Ocean Shortfin Mako Shark, Isurus Oxyrinchus, Jonathan Gorman, Nicholas J. Marra, Mahmood S. Shivji, Bryce J. Stanhope Oct 2019

The Complete Mitochondrial Genome Of An Atlantic Ocean Shortfin Mako Shark, Isurus Oxyrinchus, Jonathan Gorman, Nicholas J. Marra, Mahmood S. Shivji, Bryce J. Stanhope

Biology Faculty Articles

We report the first complete mitochondrial genome of a shortfin mako shark from the Atlantic Ocean. The genome had 16,700 base pairs and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a non-coding D-loop. There were 81 individual differences compared to the published mitochondrial genome of a shortfin mako from the Pacific Ocean, with most variability found in protein coding genes, especially ND5, ND3, and ND1. These highly variable genes may be useful population markers in future studies, and availability of a second mitogenome will assist with future, genome-scale studies of this IUCN Endangered species.

Gut Microbiome Diversity Is Associated With Sleep Physiology In Humans, Robert Smith, Cole Easson, Sarah M. Lyle, Ritishka Kapoor, Chase P. Donnelly, Eileen Davidson, Esha Parikh, Jose Lopez, Jaime L. Tartar

Biology Faculty Articles

The human gut microbiome can influence health through the brain-gut-microbiome axis. Growing evidence suggests that the gut microbiome can influence sleep quality. Previous studies that have examined sleep deprivation and the human gut microbiome have yielded conflicting results. A recent study found that sleep deprivation leads to changes in gut microbiome composition while a different study found that sleep deprivation does not lead to changes in gut microbiome. Accordingly, the relationship between sleep physiology and the gut microbiome remains unclear. To address this uncertainty, we used actigraphy to quantify sleep measures coupled with gut microbiome sampling to determine how the …

The success of reef-building corals for >200 million years has been dependent on the mutualistic interaction between the coral host and its photosynthetic endosymbiont dinoflagellates (family Symbiodiniaceae) that supply the coral host with nutrients and energy for growth and calcification. While multiple light scattering in coral tissue and skeleton significantly enhance the light microenvironment for Symbiodiniaceae, the mechanisms of light propagation in tissue and skeleton remain largely unknown due to a lack of technologies to measure the intrinsic optical properties of both compartments in live corals. Here we introduce ISOCT (inverse spectroscopic optical coherence tomography), a non-invasive approach to measure …

Diverse Deep-Sea Anglerfishes Share A Genetically Reduced Luminous Symbiont That Is Acquired From The Environment, Lydia Baker, Lindsay L. Freed, Cole Easson, Jose Lopez, Dante Fenolio, Tracey Sutton, Spencer Nyholm, Tory Hendry

Biology Faculty Articles

Deep-sea anglerfishes are relatively abundant and diverse, but their luminescent bacterial symbionts remain enigmatic. The genomes of two symbiont species have qualities common to vertically transmitted, host-dependent bacteria. However, a number of traits suggest that these symbionts may be environmentally acquired. To determine how anglerfish symbionts are transmitted, we analyzed bacteria-host codivergence across six diverse anglerfish genera. Most of the anglerfish species surveyed shared a common species of symbiont. Only one other symbiont species was found, which had a specific relationship with one anglerfish species, Cryptopsaras couesii. Host and symbiont phylogenies lacked congruence, and there was no statistical support …

Wildlife In Parks And Communities: Institutionalizing Wildlife Conservation In Park Systems Through Municipal-Wide Planning Efforts, John J. Pipoly Iii, Lajuan Tucker, Patrick Fitzgerald, Scott Gilmore

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Wildlife populations are declining in the United States. As development increases, local parks and natural areas often become safe-havens for wildlife, including birds, pollinators and small mammals. Creeks, rights-of-way, roadsides and even private, commercial and public landscapes can create corridors for wildlife in urban and suburban areas, helping wildlife survive and minimizing human-wildlife conflicts. While many park departments and municipalities have some nature or wildlife programs at nature centers and public parks or manage some properties as natural areas, most do not integrate best practices for managing wildlife into park and recreation master plans or municipalwide sustainability, green infrastructure or …

A Toolkit For Managing The Ee (Environmental Education) And Esd (Education For Sustainable Development) Continuum, Attiyya Atkins, John J. Pipoly Iii

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Environmental Education (EE) and Education for Sustainable Development (ESD) represent extremes of a global continuum. EE stresses awareness of process about, from and for the environment (Vrasidas 2007). ESD is defined as education empowering communities to acquire best management practices engendering human, social, economic and natural sustainability (UNESCO 2012) and developing their resilience despite environmental changes (Fastenrath et al. 2019). ESD is a critical component of the UN's Sustainable Development Goals (UN 2012), which grew from the Millennium Development Goals (UN 2000). Each park agency should develop research-based educational programs that address both EE and ESD. The ESD must promote …

The interdependence of diverse organisms through symbiosis reaches even the deepest parts of the oceans. As part of the DEEPEND project (deependconsortium.org) research on deep Gulf of Mexico biodiversity, we profiled the bacterial communities (‘microbiomes’) and luminous symbionts of 36 specimens of adult and larval deep-sea anglerfishes of the suborder Ceratioidei using 16S rDNA. Transmission Electron Microscopy was used to characterize the location of symbionts in adult light organs (esca). Whole larval microbiomes, and adult skin and gut microbiomes, were dominated by bacteria in the genera Moritella and Pseudoalteromonas genera. 16S rDNA sequencing results from adult fishes corroborate …
